I get that I could also move my spot to another small area. I've done this many times. However, I have found that flatland is basically a magnet it seems. I move, they follow... usually the kids. Now, I just try to stay in 'my' spot so that people aren't trying to guess where I'll be.
.I just start coughing and pretend wiping my nose ..as they look at me and theystay away from me..lolf*ck em!
